I credit my parents for many things that had never seemed remarkable when I was growing up, and one of those things is how nonthreatened they were by my constant search for backup parents - other mothers and fathers would have bristled at this, but they never did. So I was always looking for other parental stand-ins, and I always found them.

There are times I wish I didn't have a job, even though I love my job: I get to work with interesting, eccentric colleagues and equally interesting and eccentric subject matter, both of which are rarities. But, naturally, I would treasure having more freedom someday: of time and of movement. Will I always have a full-time job? I don't know. But I do know that I need to spend at least part of my week in an office, with other people.

I'm an indulgent writer - I'm not sure, however, that's something I'm interested in changing. Writing should be indulgent: you should take big risks on the page, you should make big mistakes, you should be excessive at times. I let myself do as a writer what I probably would be less likely to allow as an editor.

When you're young, your perception of what it means to be a writer is often less about the writing and more about what seems to be the accompanying life: speeches and travel and hanging out with other writers. You think that when you get published, your life will clarify itself to you somehow. But when you don't get published until you're middle-aged you know who you are already, and your life expands to make room for your writing, rather than orbiting around it. You realize that there's no one way to be a writer, and that the job is less of an identity and more of a vocation.

Of death, my father has always said that the best conditions are the ones in which you have plenty of time to prepare - to say what you need to say; to arrange your estate - and the ones in which you get to choose, or at least have some knowledge of, how and when it might happen. One can't elude death, but one can have a good death.

Sometimes the most difficult thing you can do as an editor is not make a single note - the idea that everything and everyone needs editing is, in reality, a fiction. I've gotten pieces where I thought, Well, I could do this or that, or change this word, but in the end, I leave it. Changing something is not necessarily equivalent to making the piece more true to itself, which is the point of editing: it's just changing it because you feel you can or should or must.

To be a scientist you have to be willing to live with uncertainty for a long time. Research scientists begin with a question and they take a decade or two to find an answer. Then the answer they get may not even answer the question they thought it would. You have to have a supple enough mind to be open to the possibility that the answer sometimes precedes the question itself.
